Earlier versions of Windows cannot use ReadyBoost; nor can other operating systems
(for example, Mac OS X or Linux). ReadyBoost allows you to plug a USB memory stick
or similar memory device into your PC and assign it for use as extra memory. (You can
use only one memory device for ReadyBoost at a time.) Windows stores small chunks
of frequently needed data on the ReadyBoost device, from which Windows can
retrieve the data more quickly than if the data were stored on the hard disk.
Step 2: Decide Whether to Use ReadyBoost
Look to use ReadyBoost in any of the following situations:
You??™ve already installed the maximum amount of RAM that your PC can
have, and performance is still disappointing.
Your PC doesn??™t have its maximum amount of RAM, but to increase the RAM,
you would need to replace some or all of the existing memory modules.

12 Part I: Easy
If you can easily add RAM to your PC, do so before trying ReadyBoost. RAM will give you a far
greater performance improvement. However, ReadyBoost is well worth trying, especially if you
already have a spare memory device you can use.
You??™ve borrowed someone??™s PC and find performance lacking.
Step 3: Find Memory That Will Work for ReadyBoost
ReadyBoost requires memory that can store and return data quickly enough to supplement
RAM effectively.
